Title: 90-degree phase shifter
Inventor: FUJITA KENJI
IPC: H03K5/13
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To provide a 90-degree phase shifter which can fast operate with small power consumption and also can precisely and stably extract an output signal that has a 90-degree phase difference. SOLUTION: The input signals which are complementary with each other are applied to the input terminals 5 and 6. The double-operating transistors Tr5 to Tr12 and load resistances R1 to R4 constitute a 1/2 divider and output the 90-decree phase difference signals to the output terminals 11 to 14 based on the collector currents of the signal input Tr1 to Tr2 which are corresponding to the input signals. A duty ratio monitoring load 2 converts the collector currents into voltage. An LPF 3 extracts a DC component equivalent to a shift against 50% duty ratio of the input voltage from the converted voltage. Then a DC component amplifier 4 amplifies the DC component and applies the feedback to the input terminals 8 and 9. As a result, the duty ratio of the collector current is a precisely set at 50% for each of Tr1 and Tr2.

Title: Detecting method of longitudinal bend of lead pin of component with face
Inventor: KAKUYA TADAAKI
IPC: G01N21/88
Filed: 1988-05-17
Abstract: PURPOSE:To enable the detection of a longitudinal bend of a lead pin, by setting a line to pass through the central part in the longitudinal direction of an image pattern of the lead pin, and by detecting the intersecting point of this line and the end part of the lead pin to determine the position of the intersecting point in the longitudinal direction. CONSTITUTION:A measuring line L is set on a prescribed position of an IC image picked up in an IC mounting device, and the brightness of image data D extracted along the line L shows a pattern as shown in a figure (b). Out of the image data, the data D of a part corresponding to the line L are averaged in a weighted manner to determine edge coordinates Xk of the opposite ends of each lead pin 2, and then the center coordinates of each pin 2 are determined. Then, a straight line S for sampling is set for each pin 2 through the center coordinates of the pin 2 and along the direction of the length thereof as shown in a figure (c). Since this straight line S intersects the fore end part of the pin 2 at a right angle, the brightness D of the image data are sampled along the straight line S and thereby the positions of coordinates in the direction of the length along the straight line S for sampling can be detected precisely. Subsequently, the positions of the coordinates of the fore end part of the detected pin 2 are compared for each pin 2, and thereby the amount of a longitudinal bend of the pin 2 can be detected.

Abstract: PURPOSE:To ensure stable channel selection for a TV picture receiver of a double superheterodyne system, by converting a receiving frequency into the 1st intermediate frequency with the frequency obtained by mixing the frequencies of a variable oscillator and a fixed oscillator through a mixer. CONSTITUTION:The oscillating frequency F2 of a fixed oscillator 7 and the oscillating frequency F1 of a variable frequency oscillator 11 are fed to a mixer 12 to produce a frequency F3=F2-F1. This frequency F3 is supplied to the 1st mixer 4. The mixer 4 mixes receiving frequencies f0 and F3 to produce the 1st intermediate frequency 1Ff1=f0+F3. The frequency f1 is amplified by the 1st IF amplifier 6 via a filter 5 and applied to the 2nd mixer 8. The mixer 8 mixes the f1 and F2 to obtain the 2nd IFf2=F1-f0, and f2 is amplified by the 2nd IF amplifier 9 to be delivered. The 2nd IFf2 contains no F2 and receives no effect of drift caused by the temperature change, the secular change, etc. of the oscillator 7. Then the oscillator 11 is controlled by a PLL circuit using a reference signal source. In such a way, a stable channel selection is possible with no shift of frequency.

Title: Improving method for residual stress of weld zone of pipe
Inventor: YAMASHITA TETSUO
IPC: C21D9/50
Filed: 1981-07-28
Abstract: PURPOSE:To improve the residual stresses in the weld zone of pipes with simple constitution by clamping outside sleeves fitted onto the weld zone of a butt welded joint then executing bead welding right on the weld zone on the outside circumference of the outside sleeves. CONSTITUTION:Half-split outside sleeves 3 are provided on the outside of the weld zone of a circumferentially but welded point 2 formed by build-up welding of pipes 1 in a number of layers. After the sleeves 3 are clamped with bolts 4, bead welding 5 is executed on the outside circumference of the sleeves 3. The part of the inside surface of the sleeves 3 facing the weld zone of the joint 2 is worked so as to coincide roughly with the shape of reinforcement of weld in the weld zone so that when the sleeves 3 are clamped the inside surface of the sleeves contacts approximately tightly with the outside surface of the pipes 1. The depth of penetration in the welds 5 is kept within the thickness of the sleeves 3 by regulation of heat capacity to prevent melting of the pipe 1 surface and the welded joint 2. By such treatment, the high tensile residual stresses in the welded joint are transferred to the residual stresses on the compression side and the residual stresses that can lead to generation of stress corrosion cracking are improved.

Title: Enclosed lead storage battery
Inventor: INOUE TOSHIHIRO
IPC: H01M2/16
Filed: 1985-05-31
Abstract: PURPOSE:To improve the service life of cell when employing trickle recharge by employing double layer separator composed of glass fiber layer having specific average fiber diameter and polyethylene or polypropylene fiber layer. CONSTITUTION:Double layer separator composed of glass fiber layer having average fiber diameter shorter than 5mum and polyethylene or polypropylene fiber layer having average fiber diameter shorter than 12mum is employed. Consequently, reduction of the thickness of separator is retarded even for long term trickle recharging thus to produce a separator having excellent tightness. When the average fiber diameter of glass fiber layer exceeds over 5mum or the average fiber diameter of polyethylene or polypropylene fiber layer exceeds over 12mum, the maximum hole diameter of separator will increase to cause shortcircuit of positive and negative plates resulting in deterioration of service life.

Side walls 8 are formed on the side faces of a gate oxide film 5 and gates 6 to cover the ends of the source/drain regions 7. For forming n<+> type source/drain regions 7, an n-type impurity is implanted into the nchMOSFET regions B sides to form n<+> regions 10. For forming p<+> type source/drain regions, a p-type impurity is implanted into the pchMOSFET regions A sides to form p<+> regions 12. They are heat treated to cancel the n<-> type layers due to the diffusion of the p<+> impurity beneath the side walls 8 at the pch regions A and leave the p<+> layers only.
